Types of Active Filters: There are basically four useful Types of Active Filters. Namely Butterworth Filter Chebyschev Filter Bessel Filter Elliptic Filter Butterworth Filter: The Butterworth filter has an essentially…
All Pass Filter Design: The All Pass Filter Design is one that passes all frequency components of the input signal without attenuation. Any ordinary wire can be used to perform…
Classification of Active Filters: An electric filter is often a frequency selective circuit that passes a specified band of frequencies and blocks or attenuates signals of frequencies outside this band.…
Types of Filters in Electronics: Types of filters in electronics may be of any physical form—electrical, mechanical, pneumatic, hyÂdraulic, acoustical, etc. The most commonly used filters are of the electrical…
What is a Filter Circuit?: A network designed to attenuate certain frequencies but pass others without attenuation is called a filter. A filter circuit thus possesses at least one pass…
What is Electromechanical Chopper?: Electromechanical Chopper - An ac amplifier must see ac in order to perform useful work. A fair number of chopping and modulation techniques are available to…
What is an Operational Amplifier?: An Operational Amplifier is a dc amplifier having a high gain, of the order of 104 - 108. Such an amplifier can perform summing, integration,…
Pressure Inductive Transducer: Pressure Inductive Transducer - A simple, arrangement, wherein a change in the inductance of a sensing element is produced by a pressure change, is given in Fig.…
